摘要

目的:建立清咽喷雾剂的质量控制方法。方法:采用薄层色谱法鉴别其中玄参、金银花、黄芩;采用液相色谱法测定其中穿心莲内酯的含量。结果:玄参、金银花、黄芩的薄层色谱法鉴别方法有良好的重现性、专属性;穿心莲甙内酯在48.1～240.3μg·mL-1浓度范围内线性关系良好(r=0.9999)

平均回收率为100.1%(RSD=0.32)。结论:该方法可用于清咽喷雾剂的质量控制。

Abstract

Objective:To develop the qualitative and quantitative methods for Qingyan spray.Methods:Figwort root

Honeysuckle flower

Baikal skullcap Root in the spray were identified by TLC.The content of Andrographolide was determined by HPLC.Results:The TLC methods for the indentification of Figwort root Honeysuckle flower Baikal skullcap Root was reliable and specific.The calibration curve for Andrographolide was linear in the range of 48.1～240.3 μg/ml(r=0.999 9).The average recovery of Andrographolidewas 100.1%(RSD=0.32%).Conclusions:The methods can be applied to the quality control of Qingyan Spray.
